Roamer Mcp Plugin MCP Server

roamer-mcp-plugin

Distributable Claude Code plugin for RoamerMcp — the Roamer project registry, behavioral spec database, and engineering threads MCP server. Learn more at roamermcp.mathismeadows.com.

The plugin is an optional extra on top of the hosted Roamer MCP server (https://roamer-mcp.mathismeadows.com/mcp). Connecting to that server on its own already gives every tool and workflow; installing this plugin adds eleven workflows as slash commands. Each is a slash command, but Claude can also invoke one on its own when the conversation calls for it — you don't have to type the command yourself:

• /roamer:orient — start-of-session briefing (project registry + open threads)
• /roamer:breadcrumb — end-of-session checkpoint (registry + thread updates)
• /roamer:feature — seven-step gated feature workflow
• /roamer:bug — eight-step gated bug-fix workflow
• /roamer:spec-audit — spec coverage audit
• /roamer:spec-check — hygiene checklist
• /roamer:thread-scrub — guided review and disposition of the open-thread backlog, on demand
• /roamer:release-notes — draft Internal/External release notes for a date window, review-only
• /roamer:login — sign in, or switch which identity this session uses
• /roamer:logout — sign this session's Roamer connection out
• /roamer:status — see which identity this connection is signed in as

Install

/plugin marketplace add mathismeadows/roamer-mcp-plugin
/plugin install roamer@roamer

The plugin connects to the hosted server over HTTP — no Node.js or local install. On first use, sign in with /mcp: select the plugin's Roamer server and follow the browser sign-in. To switch accounts later, use /mcp → Re-authenticate, or Clear authentication to sign out.

Keep one Roamer connection per client. If you've also added Roamer as a claude.ai connector or with claude mcp add, Claude Code treats a plugin server and a connector on the same URL as duplicates and ranks the plugin's first. Turn off any other Roamer server in /mcp so it's clear which one a session is using.

Upgrading from 1.x

Version 2.0 changes how the plugin connects. 1.x started a local bridge (npx @mathismeadows/roamer-device-auth) under the server name roamer; 2.0 connects straight to the hosted server under the server name mcp, so its tools are named mcp__plugin_roamer_mcp__<tool>. After updating:

• Sign in once more with /mcp (the bridge's cached sign-in isn't used by 2.0).
• If a server named roamer is still listed — in /mcp, or in VS Code's MCP Servers view — remove it and reload. A leftover roamer server can show an error with no output.
• Tool approvals you gave the old roamer server don't carry over to the new name.

Status

This repo is public — install directly with the commands above. New accounts are provisioned automatically on first login, but currently need manual approval before they can use RoamerMcp's tools (a beta access gate); you'll be notified once yours is enabled.

Structure

• .claude-plugin/plugin.json — plugin manifest
• .claude-plugin/marketplace.json — self-referential marketplace entry
• .mcp.json — the hosted Roamer MCP server over HTTP, under the server name mcp
• skills/ — the workflow commands above; each one reads its current instructions from the server

This repo is distribution-only — it has no server code, no tests, and no relation to RoamerMcp's internal architecture beyond consuming its public MCP endpoint.
